Lighting for the LearningEnvironment

Acuity Brands AIA #AB5101 AIA/LU/HSW

June 21-24, 2015Callaway Gardens, Georgia

Best in Class Lighting Solutions: At Acuity Brands, we deliver high-quality, energy-efficient, integrated lighting systems that improve the education experience and reduce operational costs. From the classroom to the gymnasium, from the parking lot to the laboratory, from pre-schools to grad schools, we help institutions achieve enhanced learning environments, increase energy savings, reduce operational costs and improve sustainability.

The Opportunity

Best in Class Lighting Solutions

Lighting represents 2 to 4% of school construction costs, but look at its other impact…

• Economics: After teacher salaries, utilities are the largest operating expense for school districts. And lighting is the largest consumer of electricity on campus.

• Student outcomes: Studies have shown that good lighting can improve the students’ mood, behavior and concentration.

The Opportunity

The Opportunity

$14 BillionTotal spending on energy by the nation’s educational institutions.

• That’s more than we spend on computers and textbooks combined.

• As much as 30 percent is used inefficiently or unnecessarily.

• Lighting is the largest consumer of campus electricity.

• Every dollar wasted on energy = less funding for education.

Note: Energy improvements could save 25%

The Bottom Line:

To use less energy and create a better building, we have to adopt new methods of lighting and lighting management that integrate electric lighting, natural daylighting and controls. (Contact Tim Hogan to get have a cheat sheet with key data.)

IECC• What is IECC ?

A code-intended energy standard that is updated every three years

• Who oversees it ?The ICC (International Code Council)

• Why is this topic important ?The IECC is mandatory in some jurisdictions

Codes and Standards

ASHRAE 90.1

• What is it?An energy standard that becomes code when adopted by some jurisdiction

• Who oversees 90.1 ?ANSI/ASHRAE/IES

ANSI - American National Standards Institute ASHRAE – American Society of Heating, Refrigeration and Air Conditioning EngineersIES – Illuminating Engineering Society

• Why is this topic important ?Energy & cost savingsCompliance may be mandatory (see http://www.energycodes.gov/adoption/states)

Controls

Scheduling• Manages lighting status based on time of day

• Complies with energy codes requiring automatic shutoff

• Good for larger open spaces

• Spaces occupied most of the time

• Areas where lights cannot be turned OFF for safety and security reasons

• Energy Savings

• Varies by application and occupancy

• Scheduling capabilities essential for load shedding energy management initiatives and demand response activities

Controls

Digital Lumen Management

• Constant lumen output over system life

• Maximizes energy savings

• Not over-lighting the space

Controls

Switching and Dimming• Individual control

• Multiuse group spaces

• On/off, bi-level, dimming

• Energy savings:

• 22% private office

• 16% open office

• 5% classroom

Controls

Occupancy Sensing• Turn off lights in an empty room

• Vacancy sensors, manual on, intelligent use algorithms embedded in some sensors

• Complies with energy codes requiring automatic shutoff

• Ideal applications

• smaller, enclosed spaces

• spaces that operate on an unpredictable schedule

• spaces that are intermittently occupied

Controls

Bathrooms/Small officesDesign Challenge

• Lights are always on, but space is mostly unoccupied

• Walls and partitions block some types of sensor technologies

• Infrared – detects motion in the space

• Microphonic – detects sound
